simple-format causes segfault?

[James Bergstra]

Hi,

I'd like to file a bug report on guile-1.8, but I don't know how.

I have a program that causes the guile interpreter to segfault when I output
with (simple-format), but runs properly when I replace the simple-format with
what I believe are equivalent calls to (display).

I'd like to file a bug-report. Should I
a) attach cores
b) attach cores + program text
c) attach cores + program text + data files
d) do nothing, because this another known issue 
   (is there a list of known issues?)
